Yes your need to rebuild in 9i
Not the case in 10g where Flashback DB can save your efforts in both of
the following cases
Failover to Standby -- No Need to rebuilt the Primary db from scratch
Opening Primary with Resetlog -- Standby db will be back with the use of
Flashback Db

Subject: RE: Dataguard - primary database moved to another server
Chris,
You don't change the activation number. Remember the "incarnation" that
gets reset with reset logs...
Remember, the standby is dependent on the change# and redo sequences of
the
primary. When you resetlogs, you break all of that in a big way. Just
like you can't recover until you take a new backup of the primary, the
standby can't recover until you rebuild it to match the incarnation of the
primary.
You need to rebuild the standby. If taking down the primary is a problem,
there are good notes on Metalink for building off of a hot backup.
